High-Efficiency Modulating Condensing Gas Boiler
The Dunkirk Royal CH Residential is a wall-mounted modulating condensing hot water boiler with up to 95.2% AFUE. Variable-speed modulation reduces fuel consumption and maintains precise comfort across multi-zone radiant and baseboard systems. Ideal for Chicago homeowners looking to cut heating bills and qualify for energy rebates.
The Royal CH's modulating technology adjusts output from low to full capacity based on actual heating demand — eliminating the on-off cycling of conventional boilers and delivering consistent, even heat throughout your home. Direct vent PVC venting eliminates the need for a chimney, making the Royal CH an excellent choice for homes without existing chimney infrastructure.
For Chicago homeowners with multi-zone radiant or baseboard systems, the Royal CH's modulating technology is particularly valuable. Conventional boilers cycle on and off at full capacity — creating temperature swings and wasting fuel. The Royal CH modulates output to match actual heating demand, maintaining precise comfort in every zone while minimizing fuel consumption throughout the heating season.
At up to 95.2% AFUE, the Royal CH is significantly more efficient than conventional cast iron boilers. For Chicago homeowners with high heating bills, the Royal CH can deliver meaningful fuel savings — and may qualify for energy rebates from Nicor Gas or other programs.

What's Included in the Installation
Trusted American Boiler Technology
Dunkirk has been manufacturing dependable heating equipment in Dunkirk, New York since 1928. The Royal CH condensing boiler represents Dunkirk's commitment to bringing the latest high-efficiency technology to Chicago homeowners. Modulating condensing technology delivers up to 95.2% AFUE — significantly more efficient than conventional cast iron boilers.
The Royal CH's modulating technology adjusts output from low to full capacity based on actual heating demand. This eliminates the inefficient on-off cycling of conventional boilers and delivers consistent, even heat throughout your home. For multi-zone systems, modulating output maintains precise comfort in every zone while minimizing fuel consumption.
The stainless steel heat exchanger is specifically designed for condensing operation. In condensing mode, the boiler extracts so much heat from combustion gases that they condense into liquid — a process that would corrode conventional cast iron. Stainless steel resists this condensate corrosion, providing long service life and reliable performance.
Direct vent PVC venting provides installation flexibility for Chicago homes without existing chimney infrastructure. PVC vent pipes are inexpensive, easy to install, and require no chimney — a significant advantage over conventional boilers that require chimney venting.

Frequently Asked Questions
How long does a Dunkirk Royal CH installation take?
Most Royal CH boiler replacements are completed in a single day. New installations may take one to two days depending on piping and venting complexity. D's Air & Heating minimizes disruption throughout the process.
How efficient is the Dunkirk Royal CH?
The Royal CH operates at up to 95.2% AFUE — significantly more efficient than conventional cast iron boilers at 82-84% AFUE. The modulating technology further reduces fuel consumption by matching output to actual heating demand.
Is financing available for a Royal CH installation?
Yes. D's Air & Heating offers financing options for qualified customers. Ask about current financing programs when you call for your free estimate.
Does the Royal CH require a chimney?
No. The Royal CH uses direct vent PVC venting — it does not require a chimney. This makes it an excellent choice for Chicago homes without existing chimney infrastructure.
What is the difference between the Royal CH and the Royal CO?
The Royal CH is a heat-only condensing boiler — it provides space heating only. The Royal CO is a combi-boiler that provides both space heating and domestic hot water from a single unit. If you need to replace both your boiler and water heater, the Royal CO may be the better choice.

HVAC Education — What Chicago Homeowners Should Know
How Your HVAC System Works Together
A complete HVAC system includes a heating source (furnace or boiler), a cooling source (air conditioner or heat pump), air distribution (ductwork or hydronic piping), and controls (thermostat). Each component must be properly sized and matched to work efficiently. D's Air installs and services all components as a complete system.
Chicago's Climate Demands
Chicago experiences some of the most extreme temperature swings in the country — from -20°F wind chills in winter to 100°F heat indexes in summer. Your HVAC equipment must be sized and installed to handle both extremes reliably. D's Air has served Chicago since 2009 and understands what local homes require.
The Importance of Annual Maintenance
Annual tune-ups extend equipment life, maintain efficiency, and catch problems before they become failures. A well-maintained furnace lasts 20+ years. A neglected one may fail at 12–15 years. D's Air offers annual maintenance plans for both heating and cooling equipment.
Energy Efficiency and Savings
Upgrading from a 10 SEER AC to a 16 SEER unit cuts cooling costs by roughly 37%. Upgrading from an 80% AFUE furnace to a 96% AFUE unit cuts heating costs by about 17%. Over 10–15 years, these savings typically exceed the cost difference between standard and high-efficiency equipment.
